	I am not sure whether this has appeared in this newsgroup,
	but I am posting it anyway.

	There are 10 stacks of 10 dimes. You are told that one of
	these stacks is counterfeit(i.e all 10 coins in that stack
	are couterfeits). Also given that a real dime weighs 10      
	grams and a fake one 9. Now you are asked to find out the 
	counterfeit stack by using a balance and and a set of weights
	in just ONE weighing.



	I may or may not post the solutions depending on the  number
	of correct answers posted.

Dimes weigh about 2.5 grams.
